VERTICAL-CHAMBER OVEN.

To all whom t may concern.'

Be it known that I, CARL OTTO, a citizen of the Republic of Germany, residing at Copenhagen, Kingdom of Denmark, Nr. 19 Vangehuisvej, have invented certain new and useful Improvements in the Construction of Vertical-Chamber Ovens, of which the following is a specification, .reference being vmade tothe accompanying drawings.

The invention vrefers to vertical chamber ovens with horizontal heating flues and particularly to those in which both gas and air are preheated by the waste heat of the ovens in so-called recuperators-i. e. two chambered preheaters. The preheating chambers are arranged in the prolongation of the horizontal heating flues in advance of the narrow sides ofthe oven-chambers in such a way, that the heating flues, of which one'is placed aboveY the other, are alternately connected with a preheating chamber of two compartments for air and gas, and one chamber for the waste heat. In the drawings I have shown the invention iirst in connection with single vertical ovens and With single ovens all the burners and recuperators are preferably placed on one of the narrow ,sides of the oven-chamber, while with the double ovens both narrow sides are used for this purpose. In all cases the flow of the heating gases in alternate heating flues, the one lyingy above the other, passes in opposite directions. The invention is shown in the drawings Sheets I andII in Figs. 1, 2

and 3 for single ovens and in Figs. 4 and 5 for double ovens, in which a are the vertical oven chambers with the heating liues b placed between them. In Figs. l, 2, and 3 each heating flue ,consists of two branches i. e. of the directly fired flue bland the returning flue Z22. Each flue b1 connects at its front end with a burner having a preheating chamber c for gas and a preheating chamber d Afor air; each flue b2 connects with a waste `heat chamber e, which preferably isdivided through adjustable openings g, both gas and air are heated through the partition walls between gas and air chambers c and d on one side and waste heat chambers e on the other side,

With double ovens the fines b1 and b2 form one straight flue and stretch along the whole length on the long sides of the ovens. At one end of the flues are arranged the gasand air-preheating chamber, at the other end the waste heat chamber. For each two superposed iiuesrv the location of the chambers is interohanged and the airand gaspreheating chambersare always located between two waste heat chambers.y In both single and double ovensthe heating liues are thus valternately connected in the vertical direction to an air and' gas ,preheating chamber and-to a waste heat chamber.

f In all cases the waste heat from the waste .heat chambersy is led through openings 7L 'and flues .2' to the stackflue Ic. It will also be observed that the waste heat chambers are arranged in arplurality of stories and that the preheating chambers' are arranged in a plurality of intermediate stories.

The very simple construction and easy accessibility of all parts of the new system allows an exact and leasy regulation` in all parts of the oven, and in consequence of the short and straight running of all the flues, very little resistance is to overcome and leakages between gas `and air and wasteA heat are avoided.
